No sound | ADVDD voltage below 3.3v, on pin 9 of the AD82088 sound integrated circuit, oscillating around 2.7v. | The easiest solution I found to solve this defect was to add a resistor in the RDX102 position of 0R, it is on the right side of the sound integrated circuit, close to the heat sink, thus restoring the necessary 3.3V voltage. | Eletrônica Renova |
